The following clearly and completely describes the technical solutions in the implementation manners of the present invention with reference to the accompanying drawings in the implementation manners of the present invention.
An embodiment of the present invention provides a terminal, and the terminal includes a body, a cover body, a circuit board mounted in the body, a central processing unit welded on the circuit board, a control part mounted on the cover body, and a protection switch welded on the circuit board. A hard disk slot for accommodating a hard disk is disposed in the body, the cover body is detachably mounted on the body, and is configured to seal the hard disk in the hard disk slot. The cover body is opened to drive the control part to open the protection switch, an electrical signal variation is generated due to opening of the protection switch, and after detecting the electrical signal variation, the central processing unit instructs the hard disk to perform data protection and powers off the hard disk.
Optionally, the hard disk slot is located on an end of the body, the protection switch and the hard disk slot are in adjacent positions, and the cover body covers an end part, of the body, on which the hard disk slot is disposed.
It should be noted that, the terminal may be an electronic terminal into which a hard disk needs to be inserted and from which a hard disk needs to be removed, such as a router, a network server, or a set top box. The protection switch may be a touch switch or a travel switch, and the control part used together with the touch switch or the travel switch may be rod-shaped or protruded.
It should be noted that, the electrical signal variation generated due to opening of the protection switch refers to a variation of an electrical signal from one state to another when the protection switch is opened. For example, if an electrical signal is identified by using a voltage, the electrical signal variation may be a variation from a high level to a low level or a variation from a low level to a high level. In an actual product implementation process, a manner of detecting the electrical signal variation is related to an implementation principle of an actually used protection switch, and this embodiment of the present invention sets no specific limitation.
An electrical signal variation generated when the protection switch is closed after being opened is also a variation from one state to another, and this variation is opposite to the electrical signal variation that is generated after the protection switch is opened. In this case, it indicates that the hard disk is installed into the terminal again, and the central processing unit may power on the hard disk for working again.
When the protection switch is a touch switch, the cover body and the body are locked and fastened by using a door interlock switch, and the cover body may be opened by pressing the cover body towards the body. In a process of pressing the cover body towards the body, the cover body drives the control part to press the touch switch, so that the touch switch is opened. An electrical signal variation is generated due to opening of the touch switch, and after detecting the electrical signal variation, the central processing unit instructs the hard disk to perform data protection and powers off the hard disk. In this embodiment of the present invention, the control part is rod-shaped, and the door interlock switch includes a locker mounted on a surface of the cover body and a lock cylinder that is mounted on the body and that is opposite to the locker.
When the protection switch is a travel switch, the travel switch is in a closed state when the control part is in contact with the travel switch. The cover body and the body are fastened in a magnet adsorption manner or fastened in an engaging manner by using a clamping hook and a clamping buckle, and the cover body may be directly opened relative to the body. When the cover body is being opened, the control rod is driven to depart from the travel switch, to open the travel switch. An electrical signal variation is generated due to opening of the travel switch, and after detecting the electrical signal variation, the central processing unit instructs the hard disk to perform data protection and powers off the hard disk, and the hard disk can be removed safely.
It may be understood that, to facilitate installation of the cover body and the body, a guide post is disposed on the cover body, the guide post and the control part are disposed on a same surface of the cover body, and a guide hole corresponding to the guide post is disposed in the body.
The control part and the protection switch are disposed in the terminal provided in this embodiment of the present invention, and the cover body is opened to drive the control part to open the protection switch, so that after detecting an electrical signal variation generated due to opening of the protection switch, the central processing unit instructs the hard disk to perform data protection and powers off the hard disk. Therefore, the hard disk can be powered off and stop working before being removed, thereby effectively preventing the hard disk from being damaged when the hard disk is being removed.
Referring to
Specifically, the protection switch is located on an end part of the body 51 and is adjacent to the hard disk slot 52, so that the cover body lo first operates the protection switch before the hard disk 55 is removed. The cover body lo may be a part of the body 51 and covers the body 51. The cover body 10 includes an inner surface 11 and multiple guide posts 13. The multiple guide posts 13 are disposed on a periphery of the inner surface ii. Guide holes 511 corresponding to the guide posts 13 of the cover body 10 are disposed on the end part of the body 51. The multiple guide posts 13 are inserted into the guide holes 511 correspondingly, to guide installation and positioning of the cover body 10 and the body 51.
It should be noted that, the protection switch may have multiple implementation forms, for example, may be a touch switch or a travel switch.
Referring to
The touch switch 20 is mounted on the body 51. When the touch switch 20 is being used, the switch may be opened by exerting pressure on the touch switch, and opening and closing are implemented by means of pressure change of a metal spring in an inner structure of the switch. The touch switch 20 is welded on the circuit board, the cover body 10 and the body 51 are used together to seal the hard disk 55 in the body 51 of the terminal 50, and the control rod 15 is in contact with the touch switch 20. In this embodiment, when the hard disk 55 works properly, the cover body 10 is in a closed state, and an end part of the control rod 15 is in contact with the touch switch 20 but does not trigger the touch switch 20. In this case, the touch switch 20 is in a closed state.
When the hard disk 55 needs to be removed, the cover body 10 is pressed towards the body 51 when the cover body 10 is being opened, the cover body 10 drives the control rod 15 to press the touch switch 20, to open the touch switch 20, and the touch switch 20 is opened. After detecting an electrical signal variation generated due to opening of the touch switch 20, the central processing unit instructs the hard disk to perform data protection and powers off the hard disk, to stop working of the hard disk, and the hard disk can be removed safely.
After the hard disk 55 is installed into the hard disk slot 52 again, the cover body 10 is pressed, so that the door interlock switch locks the cover body 10 on the body 51. In this process, the cover body 10 drives the control rod 15 to press the touch switch 20, so that the touch switch 20 is closed. When detecting an electrical signal variation generated due to closing of the touch switch 20, the central processing unit starts the hard disk 55, so that the hard disk 55 is powered on and works.
In this implementation manner of the present invention, the cover body 10 of the router 100 is opened to drive the control rod 15 to open the touch switch 20, so that after detecting an electrical signal variation generated by the protection switch, the central processing unit instructs the hard disk to perform data protection and powers off the hard disk 55. Therefore, the hard disk can be powered off and stop running before being removed, thereby effectively preventing the hard disk from being damaged when the hard disk is being removed.
Further, the door interlock switch 25 includes a locker 251 mounted on a surface of the cover body 10 and a lock cylinder 252 that is mounted on the body 51 and that is opposite to the locker 251. The door interlock switch 25 locks and keeps the cover body 10 on the body 51. In this embodiment, the door interlock switch 25 is a common locking and keeping structure in the prior art. The locker 251 is saliently disposed on the surface 11 of the cover body 10 and is disposed in the proximity of the control rod 15. The locker 251 is an arrowhead-shaped block body. The lock cylinder 252 is mounted on the end, of the body 51, on which the hard disk slot 52 is disposed. The locker 251 is inserted into the lock cylinder 252 and is tightly buckled by the lock cylinder 252, and the cover body 10 is tightly locked on the body 51. The locker 251 is pressed and then loosened, and the locker 251 is disengaged from the lock cylinder 252. In this embodiment, an opening action by using the door interlock switch 25 is the same as actions of opening and closing the touch switch 20 by the control rod 15. Therefore, using the door interlock switch 25 is more helpful in controlling the touch switch by the control rod 15.
When the protection switch is a travel switch, further referring to
In this embodiment, an abutting face 181 and a guide slope 182 connected to the abutting face 181 are disposed on an end part, of the control rod 18, opposite to the travel switch 30. The guide slope 182 plays a guiding role in abutting between the control rod 18 and the travel switch 30. In a closing process of the cover body 10, the control rod 18 slides over the switch roller 31 by means of guiding of the guide slope 182 until the abutting face 181 abuts against the switch roller 31. In this case, the travel switch 30 is in a closed state.
When the hard disk 55 needs to be removed, when the cover body 10 is being opened, the cover body 10 drives the control rod 18 to depart from the travel switch 30, the switch roller 31 is separated from the abutting face 181, the switch roller 31 springs, the travel switch 30 is opened, and an electrical signal variation is generated due to opening of the travel switch 30. After detecting the electrical signal variation, the central processing unit instructs the hard disk to perform data protection and powers off the hard disk, that is, stops working of the hard disk, and the hard disk can be removed safely.
After the hard disk 55 is installed into the hard disk slot 52 again, the cover body 10 covers the body 51. In this process, the control rod 18 abuts against the travel switch 30 again, and the travel switch 30 is closed. The central processing unit detects an electrical signal variation generated due to closing of the travel switch 30, and starts the hard disk 55, so that the hard disk 55 is powered on and works.
It should be noted that, the body 51 and the cover body 10 are fastened in a magnet adsorption manner. Magnets are disposed in the body 51 and the cover body 10. Alternatively, a magnet is disposed only in the cover body 10, and the body 51 is made of a metal material. Therefore, magnetic adsorption can be achieved by using the body 51 and the cover body 10.
The cover body 10 is locked and kept on the body 51 in a clamping and holding manner by using a clamping buckle and a clamping hook. The clamping buckle or the clamping hook is disposed on the periphery of the inner surface 11 of the cover body 10.
The foregoing descriptions are exemplary implementation manners of the present invention. It should be noted that a person of ordinary skill in the art may make improvements and polishing without departing from the principle of the present invention, and the improvements and polishing shall also fall within the protection scope of the present invention.
